PAPER FOLDIN 'G CARTON AND THE LIKE.

Application filed November 13, 1924. Serial No. 749,797.

T all whom it may concern:

Be it known that I, SAMUEL Bnnos'rnm, a citizen of the United States, residing at Middletown, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Paper Folding Cartons and the like, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to improvements in paper boxes, having particular reference to containers for breakable products, as eggs.

The object an improved box suitable to contain eggs in quantities, preferably a dozen to a box, -and which will be more eifective to prevent breakage of the eggs in shipping and handling incident to the distribution thereof.

A further object attained in the invention is a box made from a one-piece blank, adapted to be made by automatic or semiautomatic machinery a box suitable fornesting one unit in another, as delivered from the box formin machine, to reduce the bulk of quantity ots for shipping and storing, and easy to set up to receive ,the product',-also adapted to be easily and securely closed to insure full protection of the contents in shipping and handlin To this end my improved box 1s provided with means to support each egg fully suspended and entirely out of engagement one 'egg with another, the means for supporting the eggs being yieldable and adapted to providea cushioning element between the eggs,

and-thus to minimize shocks to-the contents of the carton received in handling.

A further feature of the invention consists in the shape of the paper box,the lid of the box being so associated with the body thereof to effect compression of the sides and of a spacing partition or. diaphragm intermediate the sides whereby each unit of the contentsis yieldingly held in place thus acting to prevent free lateral move ment thereof and all possibility of one unit contacting .withanot er and breakage resulting under normal conditions of handling.

These features and the details of construction of the improved paper box comprised in the improvements are illustrated 1n the accompanying drawings, described in detail attained in the invention is in the following specification and defined in-their coordinated relationone part with another in the appended claims.

In the drawings:

Fig.1 is a diagram illustrating the manner of cutting the box blanks to minimize waste of material;

Fig. 2 is a view illustrating the manner of nesting the boxes for handling in bulk;

Fig. 3 is view of the box open with the diaphragm folded ready to be adjusted in the box; e

Fig. 4 isa perspective view of the box open ready for use;

Fig. 5 is a cross-sectional view of the box;

Figs. 6 and 7 are side and end views respectively of the box closed;

As shown inFig. 1, the box blank consists of an integral piece adapted to be cut and scored by a single operation of a cutting and scoring press,-the blank consisting of a bottom portion 1, side portions 2-3, lid portions 45, end portions 6--7 diaphragm portions 8-9-10, side'portion 2 being provided with a tongue 11 and lid portion 5 with slots 12 adapted to eoact one with the other for securely closing the carton, parts 8 of the diaphragm with partially severed portions 13 -44, and parts 9 with partially severed portions 15, which coact with parts 8 and 9 to support the eggs fully suspended and effectively spaced-one from another as the box is filled, closed and packed for. quantity shipments. I

he position of the eggs in the paper box is illustrated in Fig. 5. As here shown, it will be seen that the diaphragm as folded provides opposite triangular-shaped spaces 16-17 each flanked on oneside with one of the parts8 and on the opposite side with one of the parts 9, part 10 .being directed downward parallel and in contact with side 3 of the box thus serving as a support for the free end of the diaphragm and also to strengthen the'back side of the box, part 5 of the lid acting in like manner'to strengthen the front side.

It will be observed in Figs. 5 and 6 that the sides of the box are tapered, the top of the box being substantially wider than'the bottom; also that the incisions severing portions 13 and 14 one from another are at an angle, this being for the purpose of adapting the angular edges of parts 13, as the parts are pressed outward toward the sides of the box, to be in full contact with the adjacent tapered sides of the box, as the eggs are positioned between opposite parts 1315, parts 14 being between the eggs and the sides of the box, and transversely opposite parts 15-15 being pressed toward the center of the box from opposite sides into contact one with another.

It will be observed that the eggs are thus supported suspended above the bottoin of the paper box and against lateral displacement by the yieldable elements 13.15 which engage the eggs at four points, parts 14 acting as an added buffer between the eggs and the sides of the box. 7

The lid portion 4 is somewhat narrower than the open top of, the box, which has the effect upon closing the box of drawing the sides inward to some extent and of compress ing the diaphragm to alike extent which tends to increase the pressure exerted on the eggs supported between the retaining elements 1315,-this action on the contents of the box being further increased by downward pressure on the intermediate portion 18 of the diaphragm which is substantially higher than the body of the box and is thus brought into contact with the lid as the same is closed,the upward projection of the part also serving to support the lid raised suflicicntly to provide ventilation of the interior of the box.

The lid is interlocked with the body of the box in a very simple but effective manner by means of the tongue 11 which is adapted to have its opposite, laterally projected portions 11 inserted in slots 12 of lid portion 5 and thus to hold the lid securely engaged with side portion 2, a depending lip l1 severed from part 11 being adapted to be pressed inward to enable ready engagement of part 11 with the fingers to insert the tongue in slots 12.

N o novelty is claimed with respect to the ends of the carton comprising parts 6 and 7, the same being folded and fastened one to the other, glued preferably, in the usual manner.

Having described my invention, I claim:

1. A paper box comprising a member formed integrally with a side of the box and adapted to be folded within the box to form a plurality of inclined walls therein with open spaces between the walls, the free end of said member being disposed adjacent the opposite side of the box substantially parallel thereto, partially severed portions arranged in each of said walls one opposite another transversely of said spaces and adapted to support a unit of the contents of the box yieldingly therebetween, an intermediate wall or said member being higher than the sides of the box whereby upon closing of the box said higher wall is compressed by another part of the box moved into relation therewithandadded pressure is exerted yieldingly on the separately supported units of the contents of the box.

2. A paper box comprising upwardly and outwardly inclined sides, a member formed integrally with a side and adapted to be folded'within the box to form a plurality of inclined walls therein with open spaces between the walls, yieldable elements in said walls arranged oppositely one of another transversely of said spaces and adapted to support a unit of the contents of the box therebetween, a lid for the box substantially narrower than the open top of the box and adapted when closedto compress the sides and said inner walls of the box and thereby to effect added pressure on the contents of 8 the box through said yieldable element.

In testimony whereof, I afiix my signature.

SAMUEL BERGSTEIN.
